The Library of Congress will not create original RDA bibliographic records and generally will not create RDA authority records during the interim period after the US RDA Test ends on December 31, 2010 through the announcement of any implementation decision.

Some US RDA Test participants who are PCC NACO participants will continue to create RDA bibliographic records after Dec. 31, 2010. Other non-US RDA Test participants are creating RDA records now and may/will continue to create RDA records.

RDA records will be used by LC during this interim period in the following categories:

— CIP verification;
— Records created by other libraries, vendors, etc., for materials being added to LC’s collections.

In both categories, the authorized access points may be all RDA forms, all AACR2 forms, or a combination of AACR2 and RDA forms; name authority records may or may not exist in the LC/NACO Authority File.
